Hi. I’m looking at Fmod for a full duplex application on CE. I have set up a test which plays a file with FSOUND_Stream_Play and recording at the same time with FSOUND_Record_StartSample. The playback audio is being recorded into the record buffer along with the mic input, so that when I write it to disk the new file contains a copy of the file I was playing along with the new input, which is not what I’m aiming for. I want the second file to only contain the mic input. Is this possible? I can’t see any way of assigning a channel to the record functions, and I have tried playing around with setting the Play channel to different numbers.
